In a solid electrolyte capacitor in which the solid electrolyte is polyaniline or a polymer of an aniline derivative doped with a prototnic acid, a disulfonic acid represented by the general formula (1) is used as the protonic acid to enhance high-temperature endurance and humidity resistance of the solid electrolyte: <CHEM> where R is m-phenylene, p-phenylene or a C7 to C10 bridged cycloalkylene group, and n and m are independently integers from 1 to 3. Disulfonic acids of the general formula (1) are novel compounds.i |
